Spl, and cpl locked 1month before first event and if im not mistaken it might be D1 as well. D3 arent locked you can add and drop players however once a player (goes for d2 as well) is registered with a team they cant switch teams...and as far as i know Campaign Cup was locked rosters for final 2 events..,,but its on the MS page you can download the rules book from 2006 from their website
